Aftershokz Trekz Titanium Bluetooth Headphones



Good audio quality and a great fit

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

The AfterShokz Trekz Titanium Bluetooth Headphones are a nifty and well-thought-out set of bone-conducting headphones. They fit nicely, sound good and the voice recognition with your phone is also very useful. The only downside is that the on/off button can sometimes be hard to use, especially with full-finger gloves.

Wearing a set of regular headphones while riding isn't such a good idea, because they stop you hearing things – that lorry that hasn't seen you, or the guy on the TT bike coming up on your right. This is one of the reasons behind the rise of bone-conducting headphones, ideal for commuting when you're taking the same route every day and want to liven it up with music, radio, an audio book or suchlike.

I do most of my commuting rides in London, going through some of the loudest areas of the city where you need to have all your senses about you. This means my headphones not only need to have a decent volume, they also need to let me hear everything that's happening around me.

In terms of volume, the Trekz Titaniums are great. The only times when I couldn't hear them clearly was when riding around loud construction sites, where noise is so loud I doubt I would be able to hear even with regular headphones.

The sound quality is also fairly good, giving a decent amount of bass without losing the treble. It's never going to be the same as a set of noise-cancelling headphones, but they're more than fit for purpose.

Despite the volume, I found I could still hear almost everything around me, which is a strange sensation, almost like being able to hear two conversations at the same time. It certainly takes some getting used to, but once you've got the hang of it, it is simple to recognise when something is behind you. I could even hear my freewheel at the back of my singlespeed.


In addition to simply being headphones, the Trekz Titaniums also work as a hands-free kit, allowing you to make and receive calls (depending on the quality of your phone). With my iPhone 6 I could make and answer calls, change tracks, and do almost anything you can with the regular Siri service, although it's a bit strange doing that while trying to ride in a large group of commuters.

The sound quality of the calls is good from both ends, caller and receiver. I could clearly hear them in all but the most noisy conditions, with a similar performance from the microphone.

The Trekz Titaniums fit on the head through bands that loop over your ears and behind the head. There is also some grip that comes from the flex in the titanium used in the band, which shows when you take them off and they naturally curve back so both speakers are touching. This, plus the rubberised coating, creates a good grip on the head, meaning little movement or chance of them falling off. I used these on a particularly wet and bumpy mountain bike ride without them ever feeling like they would come off, and on the road they easily stay in place.

One of the best elements of the fit is that you can wear glasses at the same time, with the area that loops over the ear being slim enough to allow glasses to sit on the top.

Battery life is a claimed six hours, which seems about right. While commuting, I needed to charge them once or twice a week. You can find out how much power is remaining through the 'Audrey Says' function, which tells you system notifications through the speakers, such as battery levels and when the unit is connected to a phone.

Multi functions

Operation of the headphones comes from three buttons, two on the right arm of the device – volume down and volume up/power buttons – and a multi-function button that sits on the outside of the left speaker. The first two are fairly self-explanatory, but the one downside I found was that the vol up/power button could sometimes be a bit awkward to use, and turning the volume up or down isn't really possible with full-finger gloves, given the pressure you need to exact. The multi-function button is simple to use, and functions to answer calls, voice dial or give commands to your phone (such as using Siri).

The headphones have what Aftershokz calls 'Nanotechnology coating and watertight rubber gaskets' which provide protection against rain and sweat. Having used these on both extremely wet days and on particularly intense rides, I found that they still functioned when my head and the unit were soaking wet. The only downside when wet is that they move a little more, but this is to be expected and doesn't count against them.

With their titanium construction, the headphones are naturally light, coming in at 39g. This means they can be worn for a long time without creating much pressure on the tops of your ears, and you sometimes forget they're there; a couple of times it took me a few seconds to work out why I couldn't get the straps off my helmet after a ride, before remembering I was wearing them.

Pairing the headphones with my phone was simple, done within a few seconds. They didn’t lose Bluetooth connection at all during the review, and as long as the phone was within around 5 metres of the headphones they worked perfectly.

Their RRP of £109.95 could be seen as a bit steep, but these are at the top of the Aftershokz tree (others are available from around £40). Having used the £89.95 Bluez 2S headphones previously, as tested by Elliot, the difference is in the weight and fit, which are certainly improved in the Titaniums, and certainly justify the additional £20.

Overall, the Trekz Titanium headphones do everything that I would want bone-conducting headphones to do. They provide good sound quality, an excellent fit and have a good multi-functional element for control. Protection against the elements also works well, and they can be worn for hours without too much discomfort, which is ideal for fitness-focused headphones. Perhaps the on/off button could be less stiff, and the buttons could be easier to operate in full-fingered gloves, but this doesn't take away from what is a really good product.
